Description.' — ^^"Propodite long and narrow, parallel-sided, its 

 thickness more than half the width, about equally convex on 

 the twQi sides, smoothish, showing scattered punctures and under 

 a lens a very fine punctulation ; on both sides of the hand a row 

 of three or four small pointed tubercles run lengthwise along 

 the median convexity; lower edge bluntly biangular. Fixed 

 finger nearly double the width of the dactylopodite, pyriform 

 in section, with a row of tubercles along the grasping edge. 

 Dactylopodite oval in section, also' bearing pointed tubercles 

 opposed toi those on the fixed finger. 



Length of propodite as broken, 35 mm.; width, 11.5 mm.; 

 thickness, 7 mm." (Pilsbry.) 



Re-inarks. — "Types are No. 10,120 Coll. Wagner Free Insti- 

 tute of Science, and consist of an imperfect propodite with broken 

 dactylopodite in place, a fragment of the fixed finger, apparently 

 of the same specimen, and a fragment of another hand of larger 

 size, width 14 mm., thickness 9 mm. They were exposed by 

 breaking hard nodules which occur in the clay at Lenola. An- 

 other broken propodite is in the collection of the Academy from 

 the deep cut of the Chesapeake and Delaware canal, in Dela- 

 ware. 



The species is readily recognizable by the long, narrow shape 

 of the hand and the minute punctulation of the surface, the 

 biangulate lower edge of the fixed finger and hand, etc. It can 

 hardly be the smaller chela of H. gabbi on account oi the dif- 

 ferent surface sculpture, etc." (Pilsbry.)
